Working theory
 
 1. The series of Vortex Flowmeter is based on Von Karman’s Vortex Principle, which adopts piezoelectric 
crystal as testing components. It is a new kind of stress detecting vortex flow meter.It has the advantages 
of wide range rate, high accuracy,low pressure loss, good medium generality, pulse signal output 
proportional to flow, convenient to connect with computer etc.As the detector probe of sensor and the 
vortex generating body are installed separately, and the high temperature resistant piezoelectric crystal 
does’t contact with medium, so the instrument is of simple structure, good generality, and high stability.
